In 'Who Said Hello?', you play as a disgraced detective who has returned to their hometown to solve a string of bizarre and humorous encounters that have left the community scratching their heads. The townsfolk have started receiving an anonymous, unsigned greeting—each note begins with 'Hello!' and continues with increasingly absurd demands. Unraveling this riddle will involve piecing together comical town history, engaging with eccentric characters, and navigating a series of intertwined zany events. Players must choose wisely how to respond to the townspeople to gather clues while evading the hilariously incompetent local authorities who seem more interested in their donut supply than the investigation. Will you uncover the source of the mysterious greetings before it drives the town mad, or will you be the next to say 'hello' to chaos?
